Purpose: Papillary thyroid cancer (PTC) has good prognosis with a very low chance of mortality. The prognostic role of metastatic lymph node location was judged controversial and more recently (TNM VIII ed.) was considered to have no impact on the prognosis of older patients. The aim of the study was to evaluate the role of metastasized node location on PTC-related mortality. Methods: PTC-related mortality was analysed in a consecutive retrospective series of 1653 PTC patients followed at our Thyroid Clinic (mean follow-up 5.9 years). Results: Sixteen out of 1653 patients (0.96%) died because of PTC. Average age was 68 years at presentation and 74.7 at death. F/M ratio was 1:1. The death rate increased in relation to the lymph node status: 0.2% in N0, 0.3% in N1a and 3.0% in N1b. Conclusions: The presence of lymph node metastases in the N1b compartment should be considered as a risk factor for distant metastatic spread and for cancer-related death and included in post-surgery evaluation.
